Time to put Taiji's 1 rank in Prof(gambler) to use.
Here are the odds he's giving for Claude Spotting:
Bugbear/Drow/Gnoll/Kobold/Goblin/Wug/Amatine Gnome/Retsunagi 20/1
Dwarf 50/1
Elf (non-Drow) 5/1
Gnome, Ice 50/1
Gnome, Plateau 2/1
Gree 2/1
Half-Elves 1/1
Half-Orcs 8/1
Halflings 4/1
Human, Horarian 1/4
Human, Islander 1/1
Human (other) 1/2
Lizardfolk, Gatori 3/1
Lizardfolk, Sandoo 5/1
Lizardfolk, Vass 2/1
Nipit 5/1
Orc 10/1
Sakor'akai 5/1
Senyohafa 4/1
Taiji's smart enough to not accept bets that he couldn't back. If any category is getting too much action, odds will be adjusted.
